A restraining device for restraining a wheelchair in a cabin area on board of an aircraft. The device comprises a beam-like base structure being elongate in a beam extension direction, at least two floor connectors attached to the base structure and at least one restraining connector attached to the base structure. The floor connectors are spaced apart from each other in the beam extension direction. The floor connectors are configured to temporarily mount the base structure to a seat rail floor support in an aircraft cabin. The restraining connectors are configured to be temporarily connected to a structural part of the wheelchair to hold the wheelchair in place with a passenger seated therein.

Apparatus for adapting aircraft floors and related methods are disclosed. An example floor of an aircraft includes a floor beam, a seat track, and a cap coupled to the seat track. The cap is disposed over the seat track and the floor beam. The example floor includes a floor panel aligned with the cap.

Example lie-flat passenger seat configurations for transportation are described. A non-elevated passenger seat includes a seat base and a seatback pivotably connected to the sliding bar. The seat base may be opened upwardly or downwardly. The seatback may be opened sideway such that a space originally used for seat base and seatback is converted to a passage accessible by the passenger. An elevated-height passenger seat also includes a seat base, a seatback pivotably connected to the seat base, and a hinge at an upper portion of the seatback. The elevated-height passenger seat may rotate upwardly around the hinge. When the elevated-height passenger seat rotates upwardly, the elevated-height passenger seat transitions from a seating position to an elevated position with the seat base and the seatback forming a flat bed such that the passenger can lie flat on the flat bed formed by the seat base and the seatback.

A static aircraft seat privacy panel may include a body. At least a portion of a surface of the body may be shaped to at least partially conform with at least a portion of an aircraft seat. A lower edge of the body may be configured to couple to a floor via a set of floor-mounted components. The set of floor-mounted components may be within the floor separate from a set of seat tracks of an aircraft seat compliant with 16G force requirements for aviation transport. An upper edge of the body may be configured to be offset a selected distance from a surface of one or more overhead structures of the aircraft cabin when the body is coupled to one or more structures positioned proximate to a ceiling of the aircraft cabin. The static aircraft seat privacy panel may be compliant with 9G force requirements for aviation transport.

A modular passenger seat system includes a passenger seat having a seat leg with a distal end portion. The distal end portion includes a tube. The tube includes a sidewall having a first aperture and a second aperture. The modular passenger seat system includes a first detent member and a second detent member disposed within the first aperture and the second aperture in the sidewall of the tube. Each of the first detent member and the second detent member is configured to extend through the first aperture and the second aperture when the tube is received within the bushing. The modular passenger seat system includes a shaft movably disposed within the seat leg. The shaft has a lower end which when displaced against a biasing member enables the first detent member and the second detent member to retract inwardly into the tube.

A powered seat-base release system includes a rod rotatably mounted in a bucket assembly of an aircraft seat and a motor mechanically coupled to the rod. The motor is configured for rotating the rod from a locked position to a released position. A locking mechanism is configured for preventing motion of the bucket assembly. A cable has a first end and a second end, the first end being mechanically coupled to the rod, and the second end being mechanically coupled to the locking mechanism. A user interface is configured to activate the motor for rotating the rod to the released position such that the rod pulls the cable thereby releasing the locking mechanism to enable motion of the bucket assembly. Upon deactivation of the motor, a biasing mechanism is configured to counter rotate the rod from the released position to the locked position thereby back driving the motor.

A passenger seating assembly with an integrated cabin attendant seat (CAS) is disclosed. In embodiments, a CAS folds down from a monument mounted to the cabin floor via a combined track fitting that secures into the left-side or right-side track rail. A group of passenger seats (e.g., two to five) faces opposite the CAS monument and includes left-side and right-side leg assemblies mountable to the track rails via track fittings. One rear portion of a leg assembly attaches to the combined track fitting to integrate the passenger seats and CAS monument, eliminating unused space between the passenger seats and CAS monument.

A passenger seat or group of seats includes a tray table set into the armrest on either side of the associated seat, the tray table capable of translating lengthwise along the armrest and pivoting between a stowed configuration and a deployed configuration. In the stowed configuration, the tray table extends vertically above the armrest and may be stowed between (and partially behind) the associated seat and an adjacent seat, serving as a partial barrier between the two seats. In the deployed configuration, the tray table extends horizontally across the associated seat for use by the occupying passenger. The tray table is padded on its underside to provide the passenger with head and shoulder support when in the stowed configuration.

An aircraft seat may include an upper aircraft seat assembly, a lower aircraft seat assembly, and a frame actuation assembly configured to actuate the upper aircraft seat assembly relative to the lower aircraft seat assembly. The lower aircraft seat assembly may include at least one spring coupled to a foundation with a sloped actuation surface configured to cause the upper aircraft seat assembly to be at a decreased height when in a bed position. The compressing of the at least one spring may be configured to counterbalance a load within the aircraft seat and generate a controlled actuation of the upper aircraft seat assembly from an upright position to the bed position. A return force provided by the at least one spring may assist the frame actuation assembly during actuation of the upper aircraft seat assembly from the decreased height of the bed position to the upright position.

An aircraft seat kit with one aircraft seat, and an aircraft seat and cabin arrangement with at least two aircraft seats for being mounted one after the other onto a seat rail are described. The seat rail provides a grid with a pre-determined grid pitch for mounting the at least two aircraft seats. Each of the at least two aircraft seats includes: a seating structure, a support for supporting the seating structure, and one of two types of seat rail adapters for mounting the support onto the seat rail. The two types of seat rail adapters differ from each other in that they configure at least one aircraft seat with a different distance in a longitudinal direction between a seat reference point and a reference mounting position, respectively.
